LTC1094ACN#PBF

ADCs/DACs - Special Purpose Overview

The LTC1094ACN#PBF is an 8-channel, 10-bit serial I/O data acquisition system manufactured by Analog Devices Inc. It integrates a switched-capacitor successive approximation A/D core with software-configurable analog multiplexers and on-chip sample-and-holds. The device supports unipolar and bipolar conversion modes via a synchronous half-duplex serial interface compatible with most microprocessor ports. Key electrical specifications include a maximum supply current of 2.5mA (typical 1mA), a total unadjusted error of –1LSB for the A grade over temperature, and a fast conversion time of 20ms. It operates from a single 5V or 10V supply, or a –5V supply.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific package variant against the datasheet; the ACN suffix typically denotes a 20-lead PDIP package. Confirm active status and lead compliance through official Analog Devices documentation prior to integration. Ensure supply voltage requirements match the application's power architecture.

ADCs/DACs - Special Purpose Selection Notes

Select the LTC1094 when eight analog channels are required within a single component. Compare channel count and pin compatibility against the LTC1093 (6-channel) if fewer inputs suffice. Verify that the serial interface timing meets the microprocessor's clock speed constraints, specifically the 0.5MHz maximum frequency at 5V supply.

ADCs/DACs - Special Purpose Part Context

This component belongs to the LTC109x family of data acquisition systems, which includes the LTC1091 (2-channel), LTC1092 (1-channel), and LTC1093 (6-channel). These devices share a common architectural core but differ in multiplexer channel count and pinout configurations to suit varying complexity levels in embedded sensing applications.
